Commentaire sur La Genèse 18:22

ויפנו משם AND [THE MEN] TURNED FROM THENCE —from the place where Abraham had accompanied them.

Avraham was still standing. Even after the angels arrived in Sedom he did not give up but remained standing in prayer and supplication.

ויפנו משם, this is how it appeared to Avraham in his prophetic vision, i.e. that he had accompanied the angels some distance and after the appropriate distance, the angels turned in a different direction and went away. The angel who had brought the message to Sarah disappeared, whereas the other two proceeded in the direction of Sodom.
